Numlock not active on start
Have you ever had users or self been annoyed about NumLock being disabled everytime you start up Windows?
Here is the cure
Open registry (Run -> regedit)
Go to HKEY_USERS\.Default\Control Panel\Keyboard\
Right click InitialKeyBoardIndicator and change value to 2 (2 is enabled, 0 is disabled, 1 is enabled after logon i think)
Or download the regkey here and doubleclick it, accept the changes and reboot.
